Corrosion Properties of Castables with Various Calcium Oxide Content

Abstract

This article is focused to investigate the corrosion resistance of LCC, ULCC and NCC. Castables microstructure is one of the key factors influencing corrosion resistance, therefore new fine matrix was designed. Potassium carbonate was used as a corrosive medium using static crucible method for tested castables. The corrosion mechanism was evaluated by Scanning Electron Microscopy (SEM) with EDX probe. The experimental results disclosed that corrosion resistance was improved with decreasing calcium oxide content of tested castables.
